Larry Rush, 40, will not face upgraded charges after the death of his girlfriend who was stabbed during a domestic violence attack, officials said.

The medical examiner has ruled that a Jersey City woman stabbed a dozen times last year died of natural causes Saturday and her alleged attacker will not face upgraded charges, officials said today.

Alisia Walker, of Williams Avenue, was stabbed at her home on Feb. 20, 2010 and rushed to the Jersey City Medical Center in critical condition, Hudson County Prosecutor Edward DeFazio said. She was admitted, treated and eventually released, DeFazio said.

Her husband, Larry Rush, 40, is charged with attempted murder, aggravated assault and weapons offenses in connection to the stabbing, officials said. He has been in the Hudson County jail since his arrest shortly after the stabbing and he awaits trial, DeFazio said.

The couple's daughter, Sasha Walker, described her mother as hardworking, educated, and a family person dedicated to her three daughters and grandson. She said her mother suffered from multiple sclerosis for years and had been in and out of the hospital prior to her death.

Walker said today that she still has a relationship with her father and "He was someone who was struggling with addiction but before that, he was a father."

Walker said her father was a diesel mechanic for a large corporation who paid for his children to attend Islamic school and bought a home for the family.

"He took us shopping, talked to us, and even had us shovel people's driveways so we would learn the value of a dollar," Walker said of her father before his life took a bad turn.

Rush was in prison from April 20, 2007 to June 9, 2008 and Dec. 9, 2008 to Jan. 24, 2009, for drug offenses, state corrections records say. He also has a conviction for aggravated assault, officials said.

Walker said her mother was born and raised in Jersey City and had a master's degree from St. Peter's College.

"She always kept a smile on her face," Walker said. "She didn't hate anyone. Things were forgiven and forgotten and we were able to keep our family together. She was a wonderful woman."
